Description

Technical Field

[0001] This utility model relates to the field of medical nebulizer equipment technology, and more specifically, to a nebulizer. Background Technology

[0002] A nebulizer is a device used to convert liquid drugs into tiny aerosol particles, which are then inhaled by patients through the respiratory system. The nebulizer compresses air through a small tube to form a high-speed airflow, which generates negative pressure to deliver the nebulized drug through the drug delivery channel. Under the impact of the high-speed gas, the drug is formed into atomized particles, thus producing the drug atomization effect.

[0003] However, in existing nebulizers, the compressed air is always on during the nebulization process. Therefore, when the patient inhales, the nebulized medicine can enter the body through the mouth and airway; but when the patient exhales, the nebulized medicine continues to be supplied, resulting in waste of medicine and poor nebulization effect. Utility Model Content

[0004] Therefore, in order to solve the problem of drug waste caused by the continuous supply of nebulized medication during patient exhalation, this utility model provides a nebulizer, the specific technical solution of which is as follows:

[0005] A nebulizer includes a nebulizer body, a one-way breathing valve, and a mouthpiece. The nebulizer body contains an air intake channel, a nebulization channel, and a nebulization chamber arranged sequentially inside. The one-way breathing valve is inserted into the nebulizer body and contains a valve body, a ventilation chamber, and an exhalation diaphragm. The valve body and the ventilation chamber are interconnected. The exhalation diaphragm is movably installed between the valve body and the ventilation chamber. A one-way diaphragm is disposed on the inner sidewall of the valve body, located between the air intake channel and the nebulization channel. The mouthpiece is installed on the sidewall of the nebulizer body and communicates with the nebulization chamber.

[0006] The aforementioned nebulizer, equipped with a one-way breathing valve, enables unidirectional gas transmission. When the patient inhales, the one-way diaphragm opens, allowing compressed gas to be transmitted normally. When the patient exhales, the one-way diaphragm closes, the air inlet channel closes, and compressed gas transmission stops. The one-way breathing valve controls the delivery and cessation of compressed gas transmission based on the different inhalation and exhalation times, ensuring that the nebulizer is more suitable for human breathing characteristics. This improves the efficiency of drug nebulization and solves the problem of drug waste caused by continuous supply of nebulized medication during patient exhalation.

[0007] Furthermore, an air density sensor connected to the atomizing cavity is also provided inside the atomizer body, and the air density sensor is provided with a sensor interface.

[0008] Furthermore, a connection port is provided on one end of the atomizer body, one end of the connection port is connected to the air intake channel, and the other end of the connection port is connected to an external compressed gas pipeline through a flexible hose.

[0009] Furthermore, a medicine storage chamber for storing the medicine is provided between the atomizing channel and the atomizing cavity.

[0010] Furthermore, the one-way breathing valve is also provided with a control channel, one end of which is connected to the air intake channel, and the other end of which is connected to the air exchange chamber through an annular groove.

[0011] Furthermore, a circular hole is formed on the annular groove.

[0012] Furthermore, the one-way breathing valve is also provided with a pressure sampling channel, which is connected to one end of the valve body.

[0013] Furthermore, a communication port is provided at the other end of the valve body, and the exhalation diaphragm is in close contact with the communication port and can move relative to the valve body.

[0014] Furthermore, the one-way breathing valve is connected to an exhalation valve for accessing the atmosphere. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0022] like Figure 1 As shown, an embodiment of the present invention provides an atomizer comprising an atomizer body 1, a one-way breathing valve 2, and a mouthpiece 3. The atomizer body 1 contains an air intake channel 11, an atomization channel 12, and an atomization chamber 13 arranged sequentially inside. The one-way breathing valve 2 is inserted into the atomizer body 1 and contains a valve body 21, a ventilation chamber 22, and an exhalation diaphragm 23. The valve body 21 and the ventilation chamber 22 are interconnected. The exhalation diaphragm 23 is movably installed between the valve body 21 and the ventilation chamber 22. A one-way diaphragm 211 is provided on the inner wall of the valve body 21, located between the air intake channel 11 and the atomization channel 12. The mouthpiece 3 is installed on the side wall of the atomizer body and communicates with the atomization chamber 13.

[0023] The aforementioned nebulizer, equipped with a one-way breathing valve 2, enables unidirectional gas transmission. When the patient inhales, the one-way diaphragm 211 opens, allowing compressed gas to be transmitted normally. When the patient exhales, the one-way diaphragm 211 closes, the air inlet channel 11 closes, and compressed gas transmission stops. The one-way breathing valve 2 controls the delivery and cessation of compressed gas transmission according to the different inhalation and exhalation conditions, ensuring that the nebulizer is more suitable for human breathing characteristics, thereby improving the efficiency of drug nebulization and solving the problem of drug waste caused by continuous supply of nebulized drugs during patient exhalation.

[0024] Specifically, the mouthpiece 3 is consistent with the existing atomizer structure.

[0025] like Figure 1As shown, in one embodiment, an air density sensor 14 connected to the atomizing chamber 13 is also provided inside the nebulizer body 1. The air density sensor 14 is provided with a sensor interface 141. The air density sensor 14 can effectively determine the density based on the gas density inside the atomizing chamber 13. When the liquid medicine in the medicine tank 15 is used up, the gas density value in the air changes, which is detected by the sensor interface 141 and generates an alarm to prompt medical personnel to handle the situation promptly. The aforementioned sensor interface 141 detection and external alarm device are existing technologies and will not be described in detail.

[0026] In one embodiment, a connection port is provided at one end of the atomizer body. One end of the connection port is connected to the air intake channel 11, and the other end of the connection port is connected to an external compressed gas pipeline via a flexible hose. The air intake channel 11 can be connected to a standardized flexible hose and then to a compressed gas pipeline.

[0027] like Figure 1 As shown, in one embodiment, a medicine tank 15 for storing liquid medicine is provided between the atomizing channel 12 and the atomizing cavity 13.

[0028] like Figure 1 As shown, in one embodiment, the one-way breathing valve 2 is also provided with a control channel 24. One end of the control channel 24 is connected to the air intake channel 11, and the other end of the control channel 24 is connected to the air exchange chamber 22 through an annular groove 25.

[0029] In one embodiment, a circular hole is provided on the annular groove 25.

[0030] like Figure 1 As shown, in one embodiment, the one-way breathing valve 2 is further provided with a pressure sampling channel 26, which is connected to one end of the valve body 21. When the patient inhales, compressed gas enters the valve body 21 through the air intake channel 11 and the one-way diaphragm 211. Subsequently, a portion of the compressed gas enters the pressure sampling channel 26 to collect and analyze the gas pressure, while the remaining compressed gas is supplied to the patient through the nebulization channel 12.

[0031] like Figure 1 As shown, in one embodiment, a communication port is provided at the other end of the valve body 21, and the exhalation diaphragm 23 is tightly attached to the communication port and can move relative to the valve body 21. The tightness of the exhalation diaphragm 23 is controlled according to the pressure difference between the inside and outside of the valve body 21, thereby controlling the sealing state of the valve body 21.

[0032] like Figure 1 As shown, in one embodiment, the one-way breathing valve 2 is connected to an exhalation valve for accessing the atmosphere. Preferably, the exhalation valve is a PEEP valve.

[0033] Working principle:

[0034] When the patient inhales, compressed gas enters the valve body 21 through the inlet channel 11 and the one-way diaphragm 211. A portion of the gas in the inlet channel 11 passes sequentially through the control channel 24, the circular hole, and the annular groove 25 before entering the ventilation chamber 22. At this time, because the surface pressure of the expiratory diaphragm 23 inside the ventilation chamber 22 is greater than the surface pressure of the expiratory diaphragm 23 inside the valve body 21, the expiratory diaphragm 23 is tightly attached to the connection port and provides a sealing effect on the valve body 21.

[0035] When the patient exhales, the exhaled air passes through the nebulizing chamber 13 and the nebulizing channel 12 in sequence, generating positive pressure in the valve body 21 in the opposite direction. At this time, the gas pressure in the intake channel 11 is equal to the atmospheric pressure, and the gas pressure in the ventilation chamber 22, which is connected to the intake channel 11, is also equal to the atmospheric pressure. Therefore, due to the presence of positive pressure, on the one hand, the one-way diaphragm 211 no longer delivers compressed air to the valve body 21 through the intake channel 11, that is, nebulization stops; on the other hand, the exhalation diaphragm 23 moves and creates a gap with the connecting port. At this time, the gas in the valve body 21 enters the atmosphere through the PEEP valve connected here, realizing exhalation.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
